GAS BURNER.

Application filed January 10, 1928. Serial No. 245,675.

This invention relates to an improved gas burner applicable to many appliances but shown and described in this application as one used in glass blowing.

The invention is a burner that provides a number of small jets of flame which maintain their flame even in a strong draft as the burner is constructed to hold a part of the flame protected to an extent that enables it to rekindle the main flame when the draft is reduced or stops.

The invention is a burner that can be quickly and economically made and is cconomically operated.

The invention is illustrated in the accompanying drawings in which Figure 1 is a top view of a burner of the long type and embodying my invention with the right end shown in section. Figure 2 is a central longitudinal section with feed pipes shown in elevation. Figure 3 is a central cross section of the burner. Figure 4 isa top view of one end of an inner member and Figure 5 is a cross section of the top portion thereof. Fig- 25 are 6 is a top View and Figure 7 is a cross section of a burner of modified form.

The burner comprises a casing 10 with a slot 11 at the top and having a set of jets or openings 12 which receives gas from the inside chamber 13 of the burner. The gas is fed by the feed pipe 14 with a valve 15 and this gas is mixed with air from the pipe 16 having a valve 17 This mixture then passes through pipe 18 with the openings 19 to feed the chamber 13. The casing 10 is usually screwed directly on the pipe 18. At the bottom of the side edges of the slot 11 I provide channels 20 which are supplied with gas through the small channels 21. The channels 20 are usually continuous along the bottom of the slot 11.

In practice I usually make up the casing 10 of the outer tube 22 and the inner tube 23 with plugs 24 at the ends. The channels 20 are arranged in the top surface of the inner member 23 and the main jets12 and the small openings 21 pass through the inner member. The parts are proportioned so thatthe sides of the slot 11 partially uncover the channels 20.

In operation the main flame is provided by the jets 12 and an additional supply comes through the openings 21 and the channels 20. This additional flame is sheltered and when a draft blows outthe main flame it is at once re-lighted by the flame in the channels at the sides of the slot which channels open laterally with the bottom of the slot.

This burner corrects a marked defect in present burners of this type which require constant re-lighting as the usual factory installation is subjected to many drafts which extinguish the flame.

In Figures 6 and 7 I show a flat round type of burner in which the casing 25 is mounted on the pipe 26 and the plug 27 fits into the casing 25. The plug is bored to provide the slot 28 fed by jets 29 and the channels 30 are fed by the holes 31 and have the outlets 32 at the sides of the bottom of the slot 28.

Various modifications can be made without departing from the scope of the invention.

I claim 1. A Igas burner comprising a tubular member wit a longitudinal slot therein, an inner tubular member fitting the first member and having openings connecting its interior with the slot and having a slot partly uncovered by the slot of the first member and having an opening connecting said slot of the inner member with the interior of the inner member.

2. A gas burner comprising a casing having a slot in the top and of less depth than the thickness of the casing, the casing having perforations connecting the bottom of the slot with the interior of the casing, the

casing also having channels communicating laterally with the bottom of the slot and having openings connecting said channels with the interior of the casing. 3. A gas burner comprising a casing having a slot in the top of less depth than the thickness of the top and having openings to connect the bottom of the slot with the interior of the casing, the casing having chan nels arranged at the bottom of slot and partly registering therewith and having openings connecting the said channels with the interior of the casing.

In testimony whereof I afiix my signature.

CHARLES EISLER.
